3.4 Connection to XL 9000 Consoles
Remote mic amp prewiring has been fitted to many, but not all XL 9000 consoles. In many cases only a small
number of channels have been wired. Check which (if any) bays of the console have been prewired for remote
mic amps. Wiring can be retrofitted to any XL 9000 console if required - contact your local office or distributor
for more information. The prewiring comprises two parts – two control signals from each channel plus a relay
card that automatically switches the channel line input to the output of the XLogic Mic Amp.
Connection to an XL 9000 console is made from the 25 way ‘D’ type connector on the rear of the unit. This carries
both audio and control signals. Depending on the age of the console the audio inputs and control outputs will
either be on 96 pin Canon DL connectors (which were used on the original 24 channel ‘SuperPre’ mic amp) which
have 24 circuits of audio and control on separate connectors, or on 25 way ‘D’ type male connectors with the
same pin out as the Mic Amp unit. If the console if wired with DL connectors then a DL to 25 way ‘D’ type male
adaptor cable will be required.
Interconnecting cables may be ordered from Solid State Logic or supplied by the facility. See the block diagrams
opposite. Appendix B contains pinouts for all connectors. Appendix B also includes wiring information to build
an adaptor cable to connect the audio and control DLs to 25 way ‘D’ type connectors.
The cable used should be 8 pair individually jacketed multicore with an overall screen such as Belden 1512C.
Connectors should have metal or metallised covers. Connect the overall shield to the connector cover at both
ends.
If several units are to be mounted in the same rack then the headphone monitor and talkback bus should be
connected between the units by connecting the ‘MON IN’ and ‘MON OUT’ connectors on adjacent units, using
the supplied RJ11-RJ11 cable (SSL Part No.66C67240).
The headphone output monitors any channel selected to ‘MON’ plus an external talkback input. The talkback
input can be connected to a line level console talkback output if required. This signal is bussed between units on
the monitor link cables. Use an RJ11 to female XLR adaptor (SSL Part No. 66C67241) to connect talkback to a free
MON IN or MON OUT connector. One adaptor cable is supplied with each unit.
Once these connection have been made apply power to the unit(s). Ensure that the yellow ‘REMOTE’ LED on
the right of the front panel is lit. If it is not lit use a small screwdriver or similar to turn on the recessed ‘REMOTE’
switch below the LED.
Finally check that:
• The channel number displays on the front of the unit match the numbers of the channels the unit is
connected to.
• When you pull up the Mic Gain controls on the connected channels the ‘MIC’ LED changes colour from
red to green.
• The motorised pots and the remote controlled switches (48V, PAD and Hi-Z) operate correctly from the
XL 9000 when ‘Remote’ is selected and that they can be controlled locally when ‘Remote’ is not selected.
• When you connect a microphone to the Mic Amp input signal appears on the input of the correct channel
of the console.
